Alert system 948A-40

The Model 948A-50 Remote Alarm/Indicator continuously indicates the level of radiation at the detector site and provides a visual and audible indication of a high radiation level on an analog meter, light and Sonalert. Key Features Easy to read visual indicators Informs personnel to any change in radiological condition Analog meter, scaled to range of ratemeter Audible alarm (most with silence pushbutton) alerts operators of increasing radiation in monitored area or process stream Remote alarms are available for area and process monitors to provide a visual/audible indication of a high alarm state. Remote alarm units are also available with an analog meter scale that indicate in the range of 0 to 107 CPM or various mR/h ranges. Remote alarms for process and area monitors are driven by the associated ratemeter or Model 960 Local Control Unit, which provides both the analog signal (for the meter) and the alarm signal (for the visual and the audible indication). For ion chamber area monitors, the remote alarm can be electrically driven by the digital preamplifier. The meter of the 948A remote alarm/meter is an analog meter scale which indicates in the range of 0.1 to 107 mR/h. The light and Sonalert are actuated when the radiation level exceeds the high alarm set point of the UDR. Both models have a momentary pushbutton to silence the Sonalert. The Model 948A-40 and 948A-50 enclosures are steel. The two models are identical with the exception that the Model 948A-40 has no analog meter. The remote alarm/indicator is an optional component of the Model 945A Wide Range Ion Chamber Area Monitor.
